Would be interesting to see if they are controlling the red balance effectively. One of the issues I've heard reported frequently about manually interacting with a remote doctor for this kind of task is that the camera on a mobile is optimised to balance colours aesthetically rather than in a highly calibrated fashion - quite reasonably most (white) people prefer not to look overly red-faced but with a skin condition you want the truthful image not the flattering one!
